Returns were calculated by multiplying the 1999 yield by test weight discount paid at
the Southwest Grain Terminal located at Gladstone on August 26. The price paid on this
date was $.80/bu, assuming that the test weight was heavier than 37 lb/bu. Grain with a
test weight of 37 lb/bu was discounted $.04/bu, with an additional discount of $.04/bu per
pound down to 30 lb/bu. Below 30 lb/bu, an additional discount of $.07/bu occurred per
pound.
